Fire Trooper was an Outer Heaven mercenary who fought against Solid Snake during Operation Intrude N313.
Fire Trooper engaged Solid Snake while in the basement of Outer Heaven, guarding the elevator to the rooftops. Despite Fire Trooper's heavy advantage of an even battlefield with no cover in sight, Snake was able to take advantage of Fire Trooper's lack of bodily protection, and was able to eliminate him with a mere pistol.
